BRADSHAW, or BEAVER,rENNsnlyANIA. nssmuon cdx- PANY, or BLAWNOX, PENNSYLVANIA, ,ngoonromnoxor FLUID snr'ana'ron This invention relates to fluid separators, andparticularly to those used for purifying gases, such as steam, byseparating from the gases liquid particles and otherimpurities.

It has for one of its objects providing means for increasing theefliciency and capacity of the separators by reducing the tendency ofthe water chambers and passageways of the separator to overflow orbecome clogged, and

a particular object is to provide improved means for the passage of air,steamer other gases, from the water passageways and pipes and collectingchambers, so as to prevent interference with the free flow of the wateror other liquids.

Although the invention is applicable to various types of separators usedfor various purposes, yet, for the purpose of illustrating my invention,I have described it as applied to steam separators used for drying andpurifying the steam in boilers, and, particularly, to that type ofseparator known by the trade as Tracyfiers.

Of the accompanying drawings, Fig. 1 is an elevation of a separatormounted in a boiler, which embodies the features of my invention; Fig. 2is an enlarged transverse sectional view of the separator along the line22 of Fig. 1'; Fig. 3 is an elevation of one of the end plates of one ofthe sections of the separator; Fig. 4 is a fractionalelevation of aseparator 1n a boiler, showing a modification of my inventlon; Fig. 5 1san enlarged elevation of the end plate of the separator of Fig. 4; Fig.6 i's'an elevation of another modification.

This application is a continuation in part of my copending applicationSerial No. 211,- 286, filed August 8, 1927.

describing my invention comprises a casing 10 which is open on the sidesandhas positioned in the side openings baflies 11. The steam'which is tobe purified passes through these battles and the moisture containedtherein passes downwardly into the water passageway 12 and thenceinto adrain pipe 13. Ordinarily, the separator comprises a number of sections14, each arranged as hereinabove described, and each having a drain Theseparator which I have illustrated in:

The-waiterin this pipe is disposed of in-any suitable manner, lTrhecsteam' passingthrough the haflles 1- ntersfa steam. chamber 16 and from vthis chamberpasses through 17 into 1m inner conduit .18 from which it flows to theoutlet.

this case, a blank end plate 40 is fixed to the ordinaiy end plate 27.,This additional end plate .40 has an opening 41 therein, into which isithremded thevent pipe25. In this manner, or air is -free to passdirectly from the manifold 15 into one ofthe steam passageways '16,, andthus into the steam chamber 1(8 of the separator section. 1 FigsA and ,5illustrate a modificatian of myinventimi. in this; case, the vent p pe45enters from the npperside oaf the-boiierand passes down. into plate 4.6whichhas a forked passageway :14? oommunicatin with both-cf thesteampassageways .29 i; i

This arrangement is desirable when the conditions requirea greater drop in pressure through the drain and bent pipes than isobtained by connecting the vent pipe with the steam or water chambers ofthe purifier.

Although I have illustrated and described two end plates 27 and 40,Figs, 1 to 5, in forming the communicating passageways of the separator,yet, it is to be understood that \ordmarfly'caa'ried outside of theboiler and these two plates could be made integral or thatmodifications'could be formed with a single thickness plate; and othermodifications could be made in the various details which I have setforth, by those skilled in the art, without departing from the spirit ofmy invention as setforth in the following claims.

I claim as my invention:

fluid separator comprising a water chamber and afsteamfchambery a'drainp pe a communicatlng with said water chamber, an I end plate mounted onone end of the separa-v tor and having two openings therethroughcommunlcating with said steam chamber, :a

second-end plate having a forked passageway therein, said second platebeing fixed to said first mentioned plate with the branchesof the forkedpassageway communicatingwith the respective openings in said firstmentioned plate, and means providing communicationbetween said drainpipe and said forked passageway.

2. A'fiuid separator as claimed 'in claim 1, in which a portion of saidforked passageway is elevated above said two openings.

3. A fluid'separator comprising a water chamber anda' steam chamber. adrain pipe connected witlrsaid water chamber, an end plate mounted onone end of theseparato'r' and having an opening'therethro'ugh, saidopening communicating with said steam chamber," and means opera'tivelycommunieating with said 'opening and said drain pipe.

4: A fluid separator comprisinga water chamber and "a steam chamber,meansclosing one end of said steam'chamber and having anopeningtherethrough, a drain pipe communicating with said water chamber,a vent pipe communicating with said opening, and communicating meansconnecting said two pipes.

5. -A fluid separator comprising a plurality of sections,--connectingmeans'between the adjacent ends of two adjacent sections, said sectionsand connect ng means having communicatingwater passageways andcommunicatingsteam passageways, communicating drain pipe'cOnnec-tedrespectively with all of said passageways',-' and ajvent pipe connectingsaid drain passageways. 1 y 7 I "'testimon'y'whereof, I hereunto set'myGRANTDLBRADSHAW,
